참여 물질

반응 단계

Ethyl 5-(2-formyl-3-hydroxy-4-methoxycarbonylphenoxy)pentanoate (0.5 g, 0.0015 M) was added to 10% sodium hydroxide solution (10 ml) and stirred at room temperature for 2 hours. The reaction mixture was acidified with concentrated hydrochloric acid and the resulting solid was filtered, sucked dry, and washed with a little ethanol, then dried in a desiccator over phosphorus pentoxide to give 5-(2-formyl-3-hydroxy-4-carboxyphenoxy)pentanoic acid, 0.38 g, 90%, m.p. 165°-166° C.
